As of release 4.7.1, I decided to put all release notes in 1 document while at the same time
setting the versions of collectl-utils, colplot and colmux to the same thing.  Going forward
only colplot and colmux section will be updated.  Colgui notes will be left in place until
2014 when the entire utility will be dropped.  I also added a section for collectl-utils
3.3.1 as there has been some confusion about exactly what changed and have put it in the context
of colplot and colmus.

All older release notes will be added to their own sections for archival purposes.  Dropped
release notes older then 2.0.0 for collect-utils proper as 2007 felt old enough

Modification History

4.7.1  March 7, 2013

colplot
- dropped release notes older than 4.0.0 which are from 2006 and earlier
- no changes to colplot itself after 4.6.4

- dropped release notes older than 3.0.0 which was a complete rewrite anyway
- add 'u' and 'd' as paging commands you can type interactively if you
  don't have TermReadKey installed
- new switch: -colhelp will include numbers on top of each colum in
  multi-line mode to help identify them for when you don't have TermReadKey
  in stalled [thanks, John]
- added colmux release notes from 3.4.2 after older colplot notes
- added -keepalive with will tell ssh to send periodic keepalives, preventing
  long-lived connections from timing out and losing connectivity [thanks Vishal]

  setting the from/thru dates, timeframe for last n-minutes, or neither noting
  large directories can take awhile to scan for the date range [thanks Vishal]
- added support for colplot.conf parameter containing = since, 
  eg deftimeframe=float=30

colmux - 3.4.1

4.6.3  Jun 22, 2012
- relaxed x11 check to ONLY cases where cli used w/o --filedir option
- make margins tighter when legend or x-axis turned off
- updated INSTALL/UNINSTALL to be deal with apache2 on debian
- when legend/xaxis suppressed, reduce corresponding margin sizes
- new experimental API to allow last minute modification of standard plotting params
  by specifying a file as an email subject, but only for a single plot type.  added
  tiny and oneperpage to kit as examples to experiment with
- allow -suffix after a plot filenames date/time
- removed divisor from memory field defs in colplotlib.defsand added to plots themselves, 
  making it possible to use GB for mem plot and MB for some of the individual ones like 
  membuf and memmap
- added mask of 32 to allow limiting  y-axis to %f.1 to make less cluttered even though some
  labels repeat
- made the spacing between labels in the legend a little tighter 1.0 -> .7 so they're more likely
  to fit in single column.
- changed disk/network plot setting so that disk read/writes are never divided by 1000 and
  network packets always are

4.6.2
- added mask of 18 to definitions for plots 'swap' and 'nfsmeta'
- added mask to output for debug=2
- sort detail plots by instance names [kevin - thanks for the push]
- can now add addition plot header/extension mappings to defs files
  using <extmaps> stanza
- added debug 2048 to colplotlib and enhanced debug 32 a little more too
- in colplotlib when writing to a pdf, you need to set the teminal type to
  postscript BEFORE setting the output filename
- added id/for to checkboxes so you can click on text as well [thanks justin]

4.6.1   Nov  2, 2010
- see changes to colplotlib.defs
- see changes to colplotlib.phanksh
- changed behavior for 'contains'
  - default set to ANY
  - if 'contains' contains a '[', ignore any/all and treat as a pdsh expression
- added nvidia plot definitions

4.5.1   July 24, 2010
- is 'anyall' or 'contains' used as argument take them as field defaults
- changed default directory to /var/log/collectl as a number of users prefer this
  to the example plot directory.  the 'getting started' topic in the FAQ was
  updated accordingly
- don't require ghostscript for png files, fixed error check
- deal with $email format of /dir/prefix and validate against dir

4.4.2   April 26, 2010
- need to divide the read/write KBs for disk data by 1024 in colplotlib.defs

4.4.1   December 15, 2009
- clarified copyright notice
- set $LibDir to binary directory if colplotlib.ph is there, otherwise look in
  /usr/share/collectl

4.4.0	August 21, 2009
- open source release

4.3.2	July 21, 2009
- if plotting by points, set plot type to thickness-1 since we can't change the size of default
  style 0 and DO want that when thick=1
- changed message "No files matching your selections were found" to more clearly state the
  situation
- if multiple detail files for same day were generated by using -ou and the configuration changed
  (currently this is only an issues with polyserve), colplot WILL correctly select the correct
  column numbers for each individual file, something it couldn't do before.

4.3.1   April 28, 2009
- support for remote plotting
  - 2 new switches: -addr and -href
  - new plot type of 'tty' which prints png file to tty
- removed all print statements from -help routine
- upgrade to support gnuplot 4.2, which sets canvas size in 'set terminal' and
  hardcodes 'set size 1,1'
- rookie bug - wasn't NOT masking the mask variabe with 1 so it wouldn't pick up
  any other setting.
- added new switch/webfield, thick to change thickness of plot line (so I can see it!)

4.2.1   March 15, 2009
- change to colplotlib.ph

4.2.0   January 29, 2009
- when running gnuplot on a pc, can't echo a 'set terminal' command and so we have
  to just assume png and x11 are builtin, which they seem to be with 4.2
- 2 newplots - faults and paging
- added swap in/out to swap
- added all 3 to allsum

4.1.5   December 17, 2008
- updated colplot main help file

4.1.4   December 4, 2008
- added new environmentatl plot, Power
- added date range to debug code in findFiles()
- new switch for cli, --lastmins which specifies the last minutes of data to plot
  either just prior to the last file access time OR overridden with --time.  Only
  caveat for --time is you can't specify a begin time so you need something like
  "-hh:mm" in quote so the leading - doesn't look like a switch

4.1.3   October 9, 2008
- added options for Fans and Temps
- see RELEASE-collectl-utils

4.1.2   ???
- updated a few definitions in colplotlib.defs
- name of nfs detail plot wrong.  changed it from nfsd to detnfs
- made error message about missing column name in plot file more explicit
- fixed bug in live move which caused error when crossing an hour boundary
- add from date to plot display header and if different add 'thru' as well

4.1.1   Feb 29, 2008
- added new plot types for cpu to include irs, soft, steal and intrpt
  (only changes to colplotlib.defs)

4.1.0	Feb 08, 2008
- make sure gnuplot suppots png/x11 graphics for type in invocation and
  include with -v status

4.0.2 	Nov 19, 2007
- changed ambiguous 'type -h for help' message to 'type -help...'
- was not correctly setting 'unique' on initial call to findFiles which in some 
  cases [still not entirely understood] caused an infinite loop in that routine
- had wrong name for default Lustre plots.  Should have been 'sumlus' not 'lustre'
- changed units on lustre client and OST plot data to MB instead of KB

4.0.1 	Jul 13, 2007
- enhanced some error messages
- changed nfs summary plot name, which doesn't exist, to 'sumnfs'
- fixed colplotlib.ph to handle nested macros as long as defined in right order
- nested some macros in colplotlib.defs
- when both divisors the same (ctx/int) and mulitple of 1000, append multiplier
  to title
- by default, select plot file with unique or date-stamped name formats based 
  on the type of the first one that matches selection criteria.  this behavior
  can be overridden in the CLI with -unique or -nounique
- changed search order to look for 'conf' file in current dictory, then that
  where the binary is located and finally /etc
- if you run collectl on lustre server nodes with -L to force node type(s) you 
  could end up with columns that contain only 0s if that type of service not
  running and colplot then generates empty plots.  colplotlib has been modified to
  ignore such plots
- installation now supports standard redhat/suse apache configurations
- for hosts in a cluster that end in a variable width numeric, ensure they
  collate in the correct order
- wan't picking up -ylog in command line mode

- changed user-defined plotting mechanism
- replaced sample files with different ones

- need to do double-buffering with real-time data since the pointers can
  change if a new sample comes in before old sample printed
- new switch: -hostwidth, sets the minimum host name size.  This may be
  necessary when using alaises that are shorter than hostname which themselves
  longer than the default width
- fixed problem of not dealing with non-time options correctly
- added -username which will set this as initial username for ALL hosts
  you can still override for individual hosts with @
- fixed code that checks for missing samples in real-time, single line format
  to deal with crossing midnight [thanks hank]
- had to extend timeout for pings because on failures there were issues with good nodes
  connecting back
- need to check for verbose import for remapping header in real-time display
- include '-o StrictHostKeyChecking=no -q' with all ssh commands in case host entry
  missing from known_hosts and to suppress motd [thanks bob]
- fixed problem playing back data from multiple hosts on same local machine
- extended functionality of remote host reachabilty to include ssh testing AND detection
  of collectl presence and so renamed '-noping' to '-nocheck'
- new switch, -showcolver, will cause all remore nodes to print their name/collectl
  version and exit.
- extend checking for excluding multiple systems when detail data present to include
  imported modules containing ',d'
- headers not printing correctly when just doing --import whether 's' or 'd'

Version 3.1.0
- cleaned up misleading error messages when trying to specify a host/date/time
  fields with --cols
